Title
(EN) LATCHES FOR GATES AND DOORS
(FR) VERROUS POUR PORTAILS ET PORTES
Abstract
(EN)
A latch has a displaceable latching element in a housing for engagement with a separate striker arm to be latched behind an engagement shoulder of the latching element. The housing mounts a cylinder lock to receive a key from the front. A rotor is mounted on the rear of cylinder lock and rotation of the key rotation the rotor to drive a locking element to engage and lock the latching element. The rotor may also be axial displaceable against spring biasing responsive to a rear unit pushing element whereby unlocking from a rear cylinder lock may rotate the rotor to unlock and pushing causes the latching element to be displaced against its biasing to release the striker arm. Embodiments include a gravity biased and manually opened latch and a spring biased self-locking embodiment.

Verrou comprenant un élément de verrouillage déplaçable dans un logement pouvant entrer en contact avec un bras de butée séparé, apte à être verrouillé derrière une épaule de butée de l'élément de verrouillage. Le logement comprend un canon de serrure pour accueillir une clé depuis l'avant. Un rotor est monté sur l'arrière du canon de serrure et la rotation de la clé fait tourner le rotor qui entraîne un élément de blocage, qui entre en contact avec l'élément de verrouillage et le bloque. Le rotor peut encore être déplacé axialement contre une contrainte par ressort, sous l'action d'un élément de poussée d'une unité arrière, si bien que le déverrouillage depuis un canon de serrure arrière peut faire tourner le rotor pour déverrouiller et que la poussée entraîne le déplacement de l'élément de verrouillage contre sa contrainte, pour libérer le bras de butée. Les modes de réalisation incluent un verrou ouvert manuellement contraint par gravité et un verrou autobloquant contraint par ressort.
